M-CLE: Hacked Smart Cycle

M-CLE, described as ” a physical learning environment in which synergistic artificial intelligence through the use of robots(creative agents) is employed to embellish the creativity of the child”, looks like a pretty fun toy. For those of you who haven’t figured out what it does from that quote, it is a toy that kids ride on to control a robot. That robot draws on the floor while other robots interact with it using AI. This is all made to “embellish” the child’s creative work.

To control the robot, a child rides on a Fischer Price Smart Cycle. The factory electronics were replaced with an ATMEGA168. A wireless transmitter connects to the robot, which is also powered by an ATMEGA168. While one robot is controlled by the child, the others are packed with sensors to allow them to interact with it. They use touch, ultrasonic ping detectors, and IR line detectors. You can see it all in action in the video summary.

The design is interesting, everything is bright and colorful, and the shark fins on the robots are a nice touch. We have to wonder though, with a toy to ride on, a robot to control, and 3 other robots to watch in wonder, is the child going to be too distracted to be very creative?

Power Suit For Japanese Farmers

Researchers at Tokyo University of Agriculture and Technology have been demoing a new power suit. It’s intended to be used by people hand harvesting in the farm industry. The 55 pound device supports the worker’s joints as they squat and reach. Within three years, they hope to have the cost within $10K. We’ve seen quite a few power suit devices this year, but research has been going on for many years, as you can see in our power suit roundup.

Rickshaw Pulling Robot

rickshaw

[Wu Yulu] is a Chinese farmer with no formal mechanical training. He’s been building various contraptions over the years and even accidentally burned down his house at one point. Pictured above is a walking, talking rickshaw pulling robot he built to haul himself around town. You can see a video of the mechanical man on Reuters.

The design reminds us of [Bob Schneeveis]’ Schwarzenegger towed solar chariot we saw at Maker Faire.

Robot That Shovels Snow Automatically

Those of you that live in snowier climates will drool over the I-Shovel, a battery powered robot that shovels the snow off your driveway, saving you countless hours of backbreaking labor over the course of a single winter. Its inventors claim that, despite its relatively underpowered motor, it keeps the driveway clear even in heavy snowfall; the trick, apparently, is that the robot constantly monitors the amount of snow on the driveway and springs into action whenever a significant but manageable layer has built up. Unfortunately, the I-Shovel is still a prototype, but with any luck you’ll be able to actually buy one soon. If you’re impatient, of course, you could always try building your own.

Quick Robotic Base For Netbook

This is a great example of how marketing should be done. TeleToyland and RoboRealm(currently down) have teamed up together to show you how to build a quick and easy robot base for your netbook. The build process is fairly in depth, including part numbers and links to various places to buy them. They are using RoboRealm software to control the robot, utilizing two web cams for sensory input. This should get you well on your way to having an autonomous netbook wandering around your house.

25C3: Cheap Swarm Robotics

The Formica project was our favorite presentation at 25C3. The goal is to build open source swarm robots as cheaply as possible. The team ended up building 25 robots in an assembly line fashion. With enough lead time, the price could get as low as £15 each. Each bot has two direct drive cellphone vibration motors with tiny neoprene wheels. They’re controlled by an MSP430 microcontroller. The only really specialized chip is a charge controller so the bots can charge without any intervention. They have copper skis on the front that touch the ground plane plus antennas to contact Vcc. On top of the bot are three IR detectors for both navigation and for transferring firmware updates between bots. A reflective sensor is on the underside for detecting “food”. It looks like a great design and any easy way for anyone to start researching swarm robotics.

Scratch Built Air Muscles

We first talked about air muscles in 2005 while lusting after Shadow Robotic’s dexterous hand. The pneumatic devices are known for being lightweight and compliant. They’re designed to be used in robot arms and legs. [jelengar] stumbled across this guide to building your own air muscles. We’re not exactly sure what the original source is since it reads like a machine translation. The core is a piece of silicone tubing used in aquariums. It’s sealed at one end with a bolt. Braided electrical sheathing is slid over the tube and secured using multiple wraps of 24gauge wire. They say to test it using 20psi, but there’s no mention of what the limits are.
